The Client Object Model is a new programming interface for SharePoint 2010 where code runs on a user's client machine against a local object model and interacts with data on the SharePoint Server. Client OM methods can be called from JavaScript, .NET code or Silverlight code and makes building rich client applications for SharePoint easy. (More...)

Microsoft was constantly getting request from customers for more webservices. to make it easier to get data from outside of sharepoint (for example : to show sharepoint data on your desktop, by consuming a webservices), So there are two options: 1) Request microsoft to produce more web serivices or 2) Create your own custom web services, Instead creating more and more web services over and over agin in each release, Microsoft came up with a different approach , they created someting called 'Client Object Model'.

Ans. To develop rich client side solutions, three set of client-side APIs has been introduced in the Microsoft.SharePoint.Client namespace. The three APIs are targeted for three different types of clients.1. .net Managed applications - These are used when we have to create console applications or window applications, web applications which are not running inside SharePoint Contex.2. For Silverlight applications3. ECMAScript - It is a client object model extension for using with JavaScript or JScript. This is used for creating applications which are hosted inside SharePoint. For example, web part deployed in SharePoint site can use this JavaScript API for accessing SharePoint from browser using JavaScript. (More...)

Ans. When we use SharePoint client API's to perform a specific task, the SharePoint Foundation 2010 managed client object model bundles up these uses of the API into XML and sends it to the server that runs SharePoint Foundation. The server receives this request, and makes appropriate calls into the object model on the server, collects the responses, forms them into JavaScript Object Notation (JSON), and sends that JSON back to the SharePoint Foundation 2010 managed client object model. The client object model parses the JSON and presents the results to the application as .NET Framework objects (or ECMAScript objects for ECMAScript) (More...)

Ans. Basically there are three (3) authentication options you can use when you're working with the Client Object Model in SharePoint 2010:

* Anonymous* Default* FormsAuthentication

You can specify clientContext.Authentication = Anonymous\Default\FormsAuthentication, If you do not choose an authentication method in your code, the application will default to using the client's Windows Credentials (DefaultCredentials). (More...)

This model is based on collection of objects. An object contains values stored in instance variables with in the object. An object also contains bodies of code that operate on the object. These bodies of code are called methods. Objects that contain same types of values and the same methods are grouped together into classes. (More...)

-It Controls the ASP execution environment. -It can set the Amount of time script can run before an error occurs. -Converts a virtual path to a physical path on the server. -Takes a user supplied string and encode it into proper -Format for a URL string. (More...)
